I think I get it. My original question got answered by your post, even though my question is poorly formulated. Thanks!

Thanks, I understand it now. Best wishes, James.

I see, so when they go back and find F1 and F4 (i.e. the reaction forces), then they are finding the force acting on spring 1 and 4 by the walls? Thanks.

So all net forces at the nodes are zero, since we are in equilibrium. Then can you tell what forces my book is actually referring to?

Thanks for that. Ok, then let's look at node 3. The second spring will push on node 3, so spring #2 will push #3, which in turn will push back on #2. Then why do they say the force on node 3 is zero? Is it because the net force on node 3 is zero? If that is the case, then one could also say...

Homework Statement Hi Say I have a spring system as in the attached figure (it is in equilibrium). I am a little confused about the "axial force" concept after reading an example in my book. It goes as follows: "We have the three springs, where the outer most ones are attached to a wall...

Homework Statement Hello If my data errors are normally distributed, is this the same as the data being normally distributed? I mean, by "normally distributed data errors" is meant that with 68% confidence the data lies within the true value?
